Abstract
In the functional integral formulation of real-time thermal field theory, a time-dependent canonical transformation of the integration variables can remove the chemical potential from the action. The transformation eliminates the chemical potential from the differential equation satisfied by the propagator, but the chemical potential appears in the transformed boundary conditions and the final result for the perturbative Green's functions is unchanged.
